Do you ever feel like you don't have the right emotions?

I learned last night, while I was with a large group of family members, that my uncle is probably going to die from cancer by weeks end. As you can imagine this was a very emotional and sad moment, everyone was crying and hugging. But there I stood, no tears running down my face, and almost an absence of emotion. The emotion I did feel was guilt. Guilty that I wasn’t feeling as sad as everyone else.

Am I in denial or just too shocked to feel anything? Has this ever happened to you?
